sinter furnace used in pelletizing process

The gratekiln induration machinehistory, advantages, and

The second most common pelletizing processes is the gratekiln cooler (GKC) or just gratekiln process, which is often used for pelletizing magnetite ores. This process uses a shorter grate, with part of the oxidation (when using magnetite) and sintering taking place in the kiln, which is a rotating furnace that achieves more.

lack of supply of highgrade lump ores. But the concentrates and the fine fractions of highgrade iron ore produced during mining are too fine to be used directly in a blast furnace [4,5], as they would cause difficulties in the operation of the blast furnace. Consequently, briquetting, sintering and pelletizing processes were&nbsp

Sinter plant Wikipedia

Sinter plants agglomerate iron ore fines (dust) with other fine materials at high temperature, to create a product that can be used in a blast furnace. The final product, a sinter, is a small, irregular nodule of iron mixed with small amounts of other minerals. The process, called sintering, causes the constituent materials to fuse to&nbsp

Agglomeration behaviour of steel plants solid waste and its effect on

Recycling has been the fascinating topic among the researchers for all times. The present study shows the recycling of steel plant's solid wastes as blast furnace flue dust and sludge towards agglomeration and their use in the production of sinter. These wastes consist of metal oxides and coke fines as a valuable material&nbsp

Development of carbon composite iron ore micropellets by using the

Iron ore microfines and concentrate have very limited uses in sintering processes. They are used in pelletization however, this process is cost intensive. Furthermore, the microfines of noncoking coal and other carbonbearing materials, e.g., blastfurnace flue dust (BFD) and coke fines, are not used extensively in the&nbsp
